Pillar CZ 452/453/455/457 Extended Smooth Flat Magazine Release
The Pete's Pillars PP457MRS Extended Smooth Magazine Release offers improved accessibility and comfortable operation for CZ rimfire rifles. Designed for the CZ 452, 453, 455, and 457 platforms, this precision-machined steel magazine catch features an extended profile, smooth contact surface, and durable black nitride finish.
Measuring 1.59 inches long, the PP457MRS provides additional reach compared with the standard factory magazine release, making it a practical upgrade for precision rimfire competition, hunting, recreational shooting, and rifles equipped with aftermarket chassis systems.
Extended 1.59" Design
The factory CZ magazine release features a compact profile that can be less convenient to access, particularly with certain aftermarket stocks and chassis systems.
The 1.59-inch extended design provides a more accessible contact point while retaining the familiar operation of the original magazine catch system.
Its additional reach is particularly useful for shooters who appreciate a larger, more easily located magazine control without changing the rifle's underlying magazine system.
Smooth Flat Contact Surface
The PP457MRS features a smooth, flat contact surface designed for comfortable, consistent operation.
Unlike serrated magazine catches, the smooth design provides a clean contact surface without aggressive exterior texture. The understated profile also complements the factory appearance of CZ rimfire rifles.
For shooters who prefer additional traction, Pete's Pillars also manufactures the PP457MRB Extended Bumpy Serrated Magazine Release, featuring a textured face and traditional blued finish.
CNC-Machined Steel with Black Nitride Finish
Manufactured from solid steel, the PP457MRS is precision CNC machined for consistent dimensions and a clean exterior profile.
The black nitride finish provides excellent resistance to surface wear and corrosion while giving the magazine release a uniform dark appearance.
The combination of steel construction, extended length, and smooth contact surface makes this a durable replacement component for shooters who regularly use their CZ rimfire rifles.
CZ Rimfire Rifle Compatibility
The PP457MRS is designed for compatible CZ rimfire rifles, including:
- CZ 452
- CZ 453
- CZ 455
- CZ 457
The extended profile is suitable for many factory stocks and precision chassis configurations, including compatible MDT Oryx installations.
Compatibility with heavily modified or nonstandard aftermarket magazine well assemblies should be confirmed before ordering. This product includes the replacement magazine release catch only.
